It is a well known fact that public cloud hosting is the cloud hosting solution that draws the maximum takers while the private cloud usually gets a lot of flak; in spite of the criticism, the growth of private clouds has not stopped. Recent research shows that the revenues generated from private clouds are likely to escalate in the future years compared to public clouds.

The private cloud has been severely criticized for being nothing more than a renamed and slightly more flexible data center which is privately owned. At the same time, there is no denying the fact that the private cloud platform gives client enterprises more control and privacy. Users get to enjoy far better control over the performance and security. The State of the Cloud Report released by RightScale suggests that the private cloud increased by 77% with vSphere and OpenStack as leaders of the pack. Side by side, the report also traces the growing importance of the hybrid clouds which is influencing the growth of private clouds also. So, if you are using the private cloud platform, it should give you peace of mind because regardless of the criticism, it is a rather viable alternative.

TechRepublic contributor Asay writes that there are businesses using private clouds which are actually missing out on better business opportunities because they stick to the traditional thinking and tend to overlook the recent changes. As far as the hybrid cloud goes, another contributor is of the opinion that there are no definite advantages that this form of cloud can offer you. The truth is that despite the growth of OpenStack, the revenues are not impressive when you compare these with other public cloud users like AWS.

According to reports by TechRepublic, the OpenStack cloud revenues are likely to escalate to 5.7 billion dollars and this will be led by the private clouds. RightScale reports also complement this finding, arguing that the numbers of private clouds is still steadily increasing, making this a workable and practical option for businesses. The private cloud is known to offer many benefits but critics feel that it cannot cope with market changes. Critics also find no justification for integrating the private and public clouds to create a hybrid cloud.

Private cloud hosting is here to stay because it leverages some degree of virtualization for creating cloud computing services. It does not only help you to cut down on operational costs; it also lets you allocate resources better so as to meet business needs. In the process, it helps to reduce capital costs for hardware. Cost reduction is not the key advantage of private clouds; you can also benefit from scalability, self-service, agility and speed to market etc which allows any business to scale resources to experiment. Moreover, private clouds are not always on-premise; while most of these solutions are on-premise, there may be many private clouds which are outsourced or off-premises.

Third-party private cloud hosting solutions may end up sharing data centers and equipments with others while remain isolated by a VPN or virtual private network.  Private clouds are also not only limited to IaaS; they provide high-end PaaS offerings for the developers. IaaS offer the lowest-level datacenter resources but will not change how IT is performed. So, developers can use PaaS for creating new applications and produce fundamentally-new services that are much different from the old applications. Finally, private clouds are not likely to remain private always; this is only a stopgap measure according to analysts. With years, public cloud services are going to grow and service levels will improve as will security or compliance management. The new public cloud solutions will target specific business needs and some private clouds are bound to move to public cloud environments. Moreover, most of the private clouds will gradually grow into hybrid clouds so as to expand the effectiveness of private clouds to better control public cloud services as well as third-party resources.
